[SOLVED] NOHUP terminates after terminal closed

Maniaxx · 2016-09-17 02:12:39

Hallo,
i want to start a shell script from Cinnamon starter (desktop icon). The command in the starter is: sudo /home/user/bin/myscript.sh. The script should manually start a vnc server on-demand (beside other things not relevant here. Sudo is needed for other stuff). VNC works if started manually.

This is the content of the script:

#!/bin/sh
nohup x0vncserver -display :0 -passwordfile /home/user/.vnc/passwd &
sleep 5

The vnc server (process) only lives as long as the terminal (5 seconds). The 'nohup.out' just shows 'Terminated'.

Why is this happening? How can i keep the process running after the terminal closes?

Have you just tried "exec .." ? and then don't background the process (&) but instead no nothing. The process should live on as long as your user is logged in.

Then it hangs there. Appending a '&' gives same '5 seconds' result.

Terminal? What terminal? Do you just mean the parent process?

You should probably use setsid not nohup.

Sorry, i meant the shell window that opens once you double click the icon. Not a terminal indeed.
And yes, setsid works indeed. Never heard of it but i learned something today.

Thanks!

If a shell window opens, then it is a terminal emulator. But there really shouldn't be - you should be able to set it to not open the terminal window.

Shell window is intended. It gives me feedback about proper execution. I spawn VNC, OpenVPN, NFS services, mount NTFS drives and bind mount some folders to my NFS exports. The script will close immediately due to 'set -e' if anything goes wrong. I don't want to have this stuff permanently running.
